How does the motion of the particles change when the changes from a solid to a liquid to a gas?
water changing to a solid: freezing
movement of particles: vibration in fixed positions.
arrangement: fixed positions (bonds between every particle). moving closer together
water as a liquid:
movement of particles: move about (slide past each other)
arrangement: close together with no regular arrangement
water to gas: boiling
movement of particles: free/random movement at high speeds.
arrangement: particles move further apart with no bonds between particles.

Heat is what in motion?
As energy is added to a substance, the particles that make up the substance vibrate faster. This is what causes substances to change state (solid to liquid to gas). As the particles move faster, the structure changes.
What is the particle model of matter and how does it explain the changes of state that occur with variations in temperature or pressure?
The particle model of matter describes matter as being made up of tiny particles (atoms and molecules) that are in constant motion. Changes in temperature or pressure affect the motion of these particles. With an increase in temperature, the particles move faster, leading to a change in state (e.g., solid to liquid to gas). Changes in pressure can also affect the arrangement and movement of particles, causing changes in state.
Why do particles lose their attraction and change from one state to another?
Particles lose their attraction and change states due to changes in energy levels. When energy is added or removed, particles can overcome intermolecular forces and transition from solid to liquid to gas states. This is because the kinetic energy of the particles determines their motion and ability to break away and move freely.
How does removing heat from a material change the motion of it's particles?
Removing heat from a material decreases the kinetic energy of its particles, causing them to move more slowly and come closer together. This can lead to changes in the physical state of the material, such as from a liquid to a solid.
How do the molecular energy molecular motion and overall mass of a substance change when matter changes state?
When matter changes state, the molecular energy generally increases as heat is added or decreases as heat is removed. Molecular motion increases as the substance transitions from a solid to a liquid to a gas. The overall mass of the substance remains the same throughout the phase change process, as no particles are added or removed.
What happens when the motion of particles slows?
When the motion of particles slows down, the particles will have less kinetic energy. This could result in a decrease in temperature or a phase change, depending on the substance. The particles may also start to move closer together, leading to changes in density or pressure.
Do particles in Mercury collide with one another?
All particles of all things are in constant motion. Particles in a liquid collide, but the rate is subdued by the viscosity of the liquid.
What is a measure of the motion of particles?
One measure of the motion of particles is velocity, which is the speed and direction of the particles. Another measure is acceleration, which describes how the velocity of the particles changes over time.
Determind by motion and spacing of particles?
The substance's state (solid / liquid / gas), density, temperature, etc, is determined by motion and spacing of particles.
Describe how the motion and arrangements of particles change as a substance freezes?
As a substance freezes, the particles slow down and come closer together, forming a more ordered and structured arrangement. This transition from liquid to solid is accompanied by a release of heat energy as the particles lose kinetic energy and settle into a fixed position.
What change in state involves a decrease in molecular motion?
The change from a gas to a liquid involves a decrease in molecular motion. In this phase transition, the particles come closer together, reducing their kinetic energy and resulting in a more ordered arrangement.
